Airport security footage shot last week in Istanbul shows the wife of the terrorist behind a supermarket siege in Paris, as she likely made her way to Syria just before the events in France.

A massive manhunt is under way to locate 26-year-old Hayat Boumeddiene, the common-law wife and suspected accomplice of Amédy Coulibaly, a militant Islamist who authorities say opened fire on a kosher supermarket in Paris Thursday, killing 4 people before dying in a gun battle with police.
